About
 

This wind curtain shader has been created in Unreal Engine. Currently it allows the user to modify the type of wind, or reaction to it. With a few tweaks to material instances could be used for other purposes, like flags, capes or sails. The shader is interactive through exposed material parameters, which allow the developer to modify various properties.
